Broke up with my gf but she is my haidresser

It's been a week since the breakup, I'm the dumpee. Can't get over it and still feeling sooo much pain. It's haunting me 24/7. I can't do anything, barely eat. Aside from work, all I can do is wallow in my bed, hoping that someday it will get better or that she might change her mind and we could be together again. I know I have to go no contact if I want to move on, but the problem is that she’s my hairdresser. I’m so used to getting my haircut from her that I can’t imagine going to someone else. But I afraid that letting her cut my hair would feel awkward now. Why is it so hard, maaan. It feels like I'm stuck forever in this loop of despair
